Abstract

FIELD: food industry.

SUBSTANCE: method of obtaining inulin from chicory and elecampane is proposed, including preparing the inulin-containing raw material, its mechanical cleaning, washing the roots, rhizomes, stems, their grinding and mixing. The mixed and shredded pieces of raw material are extracted twice with hot water at the temperature of 75°C for 2-3 days at constant stirring. The resulting inulin extract in mass is treated with 96% ethanol at a ratio of 1:1 by volume, with the subsequent deposition of inulin at the temperature of minus 16°C. The resulting inulin is intended for use as a food additive in manufacturing functional meat, flour and dairy products.

EFFECT: quality improvement.

Description

The invention relates to the pharmaceutical and food industries and relates to a method for producing inulin from chicory high and elecampane.

Chicory tall and elecampane are wild plants. During photosynthesis, inulin polysaccharide is accumulated in their tubers in amounts depending on the climatic conditions of growth and vegetation time. Its content also depends on the conditions and duration of storage.

Inulin is hydrolyzed to fructose monosaccharide, which is a valuable preventive food and energy product, is easily absorbed in the human body, and its use in the food industry and medicine is most promising.

Known methods for producing inulin include deep purification of each product. (Shelukhina N.P., Abaev R.Sh., Aimuhamedova GB, Book: Pectin and its production parameters. Publishing house "ILIM", Frunze. - 1987. - 109 p. Methods of production. Application. - S. 10-17; RF Patent N 2001621; A.S. USSR N 487118). So to obtain inulin, complex and harsh conditions are used (Golubev V.N., Volkova N.V., Kushalakov X.M. Jerusalem artichoke. Composition, properties, processing methods, applications. M., 1995. - P. 63-68 )

The aim of the invention is to obtain a therapeutic product of inulin from a mixture of various vegetative organs of high chicory and elecampane.

This goal is achieved by sequential extraction of inulin from various vegetative organs of high chicory and elecampane, mixing and obtaining an extract of inulin in powder for food and medical purposes.

A similar method for producing inulin has not been found in the available literature.

Inulin powder from a mixture of various vegetative organs of wild plants does not require complex and stringent technological processing conditions, which allows to simplify the technology of its production and create a product from a mixture of various vegetative organs of high and elecampane chicory, to develop a method for waste-free processing of raw materials from wild plants.

The method of producing inulin in powder can be represented as follows: preparation of the feedstock (mechanical cleaning, washing of roots, rhizomes, stems of high chicory and elecampane), grinding and mixing of the native vegetative organs of high chicory and elecampane, extraction of a mixture of various vegetative organs of high chicory and elecampane during 2 ÷ 3 days at a temperature of 75 ° C. The extract obtained is treated with 96% ethanol with precipitation of inulin at a temperature of minus 16 ° C. Subsequent purification of inulin by repeated recrystallization, drying on a substrate of food film is carried out. Inulin sediments are dried, ground and a product is obtained - inulin powder from various vegetative organs of wild chicory and elecampane plants with a yield of 25.7% per 100 g of product.

An example of a specific implementation of the method.

Roots, rhizomes, stems of chicory high and elecampane in equal amounts with a total mass of 1000 g with an initial moisture content of 72% are washed, dried, crushed, extracted, 500 g of juice is obtained, which is treated with 96% ethyl alcohol with precipitation of brownish-colored inulin at a temperature of minus 16 ° C, conduct subsequent purification of inulin by repeated recrystallization and get pure inulin in the amount of 257 g

Shredded, mixed pieces of roots, rhizomes, stems of chicory high and elecampane are extracted twice with hot water of 1500 ml each at a temperature of 75 ° C for 2-3 days with constant stirring.

Water extracts are separated from the meal through a layer of calico, the meal is squeezed. The extracts and the juice filtrate are combined, evaporated on an evaporation cup at 75 ° C to 1/10 of the original volume, then cooled to 30 ° C, 96% ethanol is added in a ratio of 1: 1 by volume and placed in a refrigerator for 2- 3 days at a temperature of minus 16 ° C.

An additional precipitate of crude inulin of a brownish tint is obtained. Precipitation from juice and from the combined extracts is dried on a substrate of cling film. A dried intermediate of the inulin fraction is obtained. The obtained dried inulin intermediate is milled, and the powder is again spread in a thin layer (1-2 cm) onto a food film substrate and dried in an oven at 75 ° C.

Get 25.7 g of the finished product of inulin in a powder of a brownish tint, odorless, the taste is not pronounced. The yield of dry product is 25.7% per 100 g of the product of this batch of chicory high and elecampane.

The resulting inulin is proposed to be used as a food additive in the manufacture of functional meat, flour, dairy and other products.
